    Column = 
    VAR __Previous = 
        MAXX(
            FILTER(
                ALL('Table'),
                [Account] = EARLIER([Account]) &&
                    [Date] < EARLIER([Date])
            ),

        )

    [Sales] -

Thank you Greg_Deckler .

Works perfectly in PowerBI. I also use same Excel data model and when I try to use the same approach in Power Pivot it doesn't work there. There it calculates the difference only for the first row?

Do you have any idea why this could be the case?
